Title: Temporary pipe fixture in wall panel - involves activating inserted pref. elastic protrusion in mouth to engage internal sides
Inventor: EGER FRIEDRICH
IPC: E04G15/06
Filed: 1979-03-09
Abstract: One mouth at least is turned towards the panel-type element, in a wall or elsewhere, in attachment of a pipe duct to such an element, esp. temporarily or occasionally. A section of a fixture device (3) connectable to the panel element (2) is sited in this mouth (12). The device is activated from the side of the panel facing away from the duct (1), to engage the duct internal walling. The section (5) protruding into the mouth can be an elastic socket which is shortened for radial widening. This provides secure inmovable pipe fixture, with mouth sealing. It is quick and easy, and can be used repeatedly.

Title: Sensitive small switching mechanism - has single lever performing two increases in force so that mechanism can be operated by few grams
Inventor: MONTEROSSO RAFFAELLO DR ING
IPC: H01H83/04
Filed: 1979-04-11
Abstract: The switching mechanism increases applied force for differential switches and has high to very high sensitivity. The mechanism can be operated by as little as a few grans and has a release travel of about 1 mm. A single lever is used to perform two consecutive increases in force and travel. First by making use of the friction between the lever and a cam cooperating with the lever, secondly, by amplifying the moment by lengthening the force arm such that the force is produced by a spring engaging the lever. The mechanism resets itself immediately after operation, the lever travelling over the surface of another lever.

Title: Electronic ignition circuit for IC engine - has threshold switch for current and integrating network with superimposed auxiliary voltage on output
Inventor: BODIG BERND
IPC: F02P3/045
Filed: 1979-04-20
Abstract: An electronic ignition circuit for an i.c. engine has a threshold switch controlling the current flow through a solid state cut-out. The switch is controlled by the peak value of the output of a signal generator. The switch comes on at a point before the peak value of the wave and switches off at a point after it. The position of the peak can be shifted to control the current in the primary winding of the ignition coil. The current in the coil is regulated by the voltage from an integrating network. An auxiliary voltage is superimposed on the regulating voltage, which depends on the peak value from the generator. It is derived from a capacitor, which is charged by the generator.

Title: Spore-less Basidiomycetes strains prepn. - by pairing a spore-less strain with a wild strain, and pairing the next two generations
Inventor: EGEL-HUMMEL GERLIND PROF DR
IPC: A01H15/00
Filed: 1979-06-15
Abstract: Sporeless strains of Basidiomycetes can be prepd. by (a) pairing a strain with a mutation for sporelessness (sp-) with a wild strain; (b) allowing the di- or hetero-karyon obtd. to fruit and collecting the spores; (c) allowing the obtd. spores to germinate individually; (d) pairing the homokaryons obtd. in (c) with test homokaryons for sporelessness and bringing the di- or heterokaryons produced to fruiting; (e) examining the fruiting bodies for sporelessness and determining which homokaryons used in (d) for pairing contained the sp- mutation; and (f) pairing to homokaryons contg. sp- to give new di- or heterokaryons, which are then brought to fruiting and the fruiting bodies finally tested for sporelessness. The most important edible fungi are Basidiomycetes, but the wild strains produce large amounts of sexual spores which can serve as vehicles for viruses, can cause allergies in humans and animals and, in the case of the species which destroy wood, can damage the environment.

Title: Control circuit for vapour extraction hood - by-passes speed control circuit when starting motor to ensure rapid start=up
Inventor: KLAMT MANFRED ING GRAD
IPC: H02P25/14
Filed: 1979-09-26
Abstract: The control circuit continuously controls the quantity of air conveyed by the extractor fan and exhibits short start-up times for the fan's ac motor whilst at the same time being cheap and simple. The motor (4) speed is controlled by a conventional speed control circuit (D). A start-up circuit (E) briefly bypasses the speed-setting component (16) of the speed control circuit when the motor is switched on. The speed control circuit resumes control of the speed after a given time has elapsed. This time is defined by the start-up circuit. The motor therefore starts more quickly than it would under the sole control of the speed control circuit.

Patent DE-2945703-A1 (DE)
Title: Automatic double stroke control - has throttle valve blocking piston for control piston, and power transfer spring
Inventor: HAEUSSER HERBERT
IPC: F15B11/15
Filed: 1979-11-09
Abstract: The control is for double acting piston/cylinder units, esp. plough turning appliances, to generate a double stroke dependent upon a pressure rise in a feed pipe. It has a control piston to connect working chambers of the unit to the feed- resp. a return pipe. A throttle valve (25) in the outlet pipe (24) of the working chamber (5) causing the second stroke phase, generates a pressure head. The pressure head charges a blocking piston (26), which stops the control piston (8) in an end position. Without a pressure head, the working chamber (27) of the blocking piston is connected via a throttle (28) to the outlet pipe downstream of the throttle valve. A spring (15) acts as power transmission between piston (3) and control rod (17), resp. rod and control piston. A weaker return spring (19) charges the control piston in the opposite direction. A control surface on the control piston may be charged hydraulically against the return spring, and has a control conduit (35). The control conduit is separated from the feed inlet (21) during the first stroke phase, and connected to it during the second phase.
Patent DE-2951988-A1 (DE)
Inventor: HUELSER JOHANN
IPC: D06C23/02
Filed: 1979-12-22
Abstract: The pattern roller has a relief-like surface patterning. The rigidity of an elongate pattern roller is approximately proportional to the fourth power of the diameter. The pattern roller is to be designed in such a way that variations in the surface pattern, with an unchanged maximum diameter (D), do not have an adverse influence on the rigidity as a whole. The problem is solved by an axial core (25) of predetermined stability, for example made of steel, and a casing (26), for example made of plastic, which does not contribute appreciably to the overall stability. <IMAGE>

Title: Design of the magnetic circuit of DC motors having electronic commutation
Inventor: ZAHN DIETER
IPC: H02K29/00
Filed: 1981-01-27
Abstract: The invention relates to the design of the magnetic circuit of DC motors having electronic commutation, especially of low-power machines, having a polarised, preferably permanent-magnetic rotor and at least three coils or coil groups in the stator. The aim of the invention is to achieve a torque which is as constant as possible over the entire rotation angle of the rotor of 360 DEG , with optimum efficiency and very favourable magnetic utilisation, in the case of motors having electronic commutation with as few stator windings as possible, and at the same time to obtain a very low ripple on the rectified generator half-cycle of the winding source voltage. According to the invention, this is achieved in that the stator laminate comprises three main poles and three auxiliary poles or in each case an even multiple thereof, the main poles and auxiliary poles being in an alternating sequence and each main pole carrying one of the coils of a coil group, while the auxiliary poles have no windings. The ratio of the width of the main poles to the width of the auxiliary poles in the circumferential direction is preferably 3:1.

Filed: 1981-04-07
Abstract: A process and apparatus for coating the interior of a fiber-reinforced tube formed of cellulose hydrate in which a tube filled with a coating liquid is passed through a special conveying and pumping device which also serves to replenish the coating liquid. Above the level of the coating liquid, the tube is inflated with a support gas and is gradually flattened. The flattened tube then travels through a metering device made up of wipers in the form of doctor blades or rollers, which retain the major quantity of the coating liquid which is present on the inside surface of the tubing so that a thin, uniform film of the coating liquid is formed. The tubing is thereafter dried to remove the volatile constituents of the coating liquid, and is subsequently wound up.
